ABe it known that I, JAMES KIEM-EY, otlChicag'o,in the county' of Cook, an'deState o i Illinoisyhave invented @non fma @aan i JAMES Kleintier, or.' enfonce, immers, l.issi-enIRy To. Einer-.LF 'Anlb -f 'fnncneRAYg-j y Lettere Patent No. 82,329, dated Septenzter22,1868.

Inirovnn cas-sinne 'errechnete' Y' A l n @311g Signale refm'eh'tn in tgt-ese Estera vrztinunwilling nf. threads;

a certain new and improved 'Mode of Operating'Raili-oad-Gar Brakes; and I do hereby declare that 'the follow- 'lingis'a-full, clear, and exact description thereof, referencefbeing had to the,accompanying-drawings, making a partofvthis'speoication,ixnwhichfef' Figure 1- is a front view of one-half of e railroadcar platform, shoivin'g a porti@ 0f the hand-Tail the hakestandard, the ratchet, and the paw'l-box'. 'I

.Figure 2 is a'lon'g'itudinal section, taken vertically through .the platform of a railroad-car, showing a. side view of the saule parts illustrated in fig. 1. c f A f Figure 3 Ais an enlarged vertical section, taken lengthwise through the pawl-box. as indicated by the course of redV line y y in 4.

Figure@ is a horizontal section through the pa'ivl-hox, 'as indicated. by the con'se of line :c in iig. 3.A Similar letters of reference indicate corresponding parts in the several figures.

Thisl in'v entiongn'e l 'The object of the invention is to proyide for enclosing the'pawl; or other equivalent releasing and arrestingdevice ofa brake-standard, within a case or bornand employing a treadle, for releasing the said pawl from its Vratchet-wheel uponthe brake-rod :when it Ais' desired to' free the brakes, said parts beingso constructed that all liability to accident is prevented from en exposure of pawl at such points, as will be hereinafter explained. y

l*Another* object of my invention is to so construct the pawl-and-ratchet tvheel of-a brake-'standardthat when the pawl'is raised free'i'rom' its ratchet, it will be automatically arrested or held in this position until the brakestandard is turnedvto .wind up the brake-schein, when said pawl will be caused to engage -with the ratche vvwheel again, seas toiretain thc brakes at any point during the act of applying them, as will be hereinafter eXained.

To enahlothersskilled in the art to understand my invention, I will describeitsconstruction and operation. .Y v l,

'fin thanncompnying draivings, represents a car-platform, B B4 thet-handireil,"'andfthefbrakefstandard or spindle, with a hand-wheel C on' its upper end, all of which parte, maybe yconstnrcted in the usual wellknonjn manner. 4

and' also by a stirrup, G, which ils-boltedto thebottoin vofthe platformA, as shown in figs. 1 and 2. These supportsallow. the standard C tobe rotated freelyveither' toward theleft or right.V l

'lo the standard C, onV top'uof the platform A, a wheel, D, is keyed, having ratchet-teeth formed upon its vupper surface, andv arebate'v in -its lower circumferential, edge, which rebate has ,a tooth, 6,*that is designed te 'serve as areleasingtrip for a'pawLfH, when itis desired tohave this -pnwl engage with the teeth of ratchet` y wheelD, as willbe hereinafter explained. 2 A The pawl H is' constrncted with a tail-extension, p, upon it, the rearextr'emty of which is adapted for receiving a lateli'ing-'poergzf as shown in iig. 3, when this pawl is free1 from the ratchet-teeth ennuh eel'D rPawl H is'pivot'edt z' to two' ears, S, formed 'on a fixed plate, g1, and through the tail-cxtension p anoblong hole-,is made for receiving through it the'vertioal stem f of a treadle, E. Y

1;., Beneath 4the"rail-extension p, and surrounding the treadle-stem f, is a coiled spring, gf, which operates to thrownp said extension, and thus engage the pawl with the ratchet-teeth on wheel De. spring, j', also surrounds the treadle-steln Within Sprngg, which isY designed for throwingr up .the treadle E when released from pressure of thefoot Vof the bralreman. Y

Both springs, gl andf; are held in place against lateral displacement hya cupped elevation'iupon the fixed plate g, as shown in fig.l 3.'

V lates to certain newL ana userul improvements on releasing and arresting-devices which I are applied to brake-standards'of railroad-cars and coaches.

- The standard C is supportedin a vertical position by an eye-bracket, a, projectingfrom the hand-rail B 2releasing the latch y2, by the act of turning saidratchet-wheel.

The latch g is pivotecl in a slot Vmade through lthe'plate g, and acted upon by a springags, so that whentthe treadle E is depressed, and the pawl 'H thus released from the wheel D, said latch will catch over the rear extremityof thetail of the paw'l, and'hold'r it in the position shown in` g. 3. When the pawl H isgthusxheld the-latch g2, the brake-standard C, with' its wheel D, is free to rotate either tothe right or left.

This latch g2 is designed -to relieve the brakeman from the inconvenience of pressing with his foot upon the treadle E during the unwindingof the brake-.chain c. from the` brake-standard. A l

For-the purpose of releasing the pawlH fromthe latch g2, a 'sliding plate, hais fitted into a recess,'n,'1nade' 1n the bottoml of the fixed platefg, and guided by studs t t, passed through on oblong slots j made through said blong plate. A short hooked stud, 1/, is secured to the rear end'of .slide h, and exteunds up through the slot Vthrough plate g, in which latch g2 ispvoted, so as to act upon .this latch.

A right-angular arm, k, is pivoted in the recessln to plate g at the opposite end-ofthe slide h, by pressing which arm in one direction, it will force 'the plate L backward, andceuse the stud h to disengage the latch fioul' pawl H, thereby allowing the spring gf to engagelthe pawl with the ratchet-teeth on wheel D. That end of the angular armk which is nearest the wheel D projects beyond the plate g, so as tobe struck by the tocth biupon the circumference of wheel D, whenxthis wheel is rotated. j

The tripping and releasing-devices, with the exception of a portion' of the ratchet-wheel. D, are enclosed wthin'a. box,"F, which, with plate g,is.bolteddown fast upon the platform, as shown in the drawings.

"This, box serves as a safety-guardtoprevent accidents, ,which frequently happen upon the platforxns of' railroadlcars, in consequence of ladies dresses catching upon the exposed pawls, as hitherto lemployed.'-`

i Said box also serves. to keeput dust7 ice,-and snow-from the enclosed devices,v and protects them from injury from any external cause.

The treadle or foot-piece'E for releasing the vpawl-from its ratchetwheel, is itted' to work ina depression, d, formed in thel crown of the boxorcaseF, and this treadle isrconstructed with shoulders, e', upon the lowe'r., f endo-f its guide-stern,L which keepjt in place withinits recess, and allow it to rise-'ilushA with the top surface off the box F when released. v While I prefer to vemploy the latchng" and releasing-devices-for the pawl, in onj unctionwith an enclosingcase for this pawlg do not confine my invdntion tothis combination; as the paw wheel and enclosing-case, may be used to advantage without said arresting and releasing-devices. Having described nlyinventiomwhat I clainasnew, and desire to secure by Letters Patent, is 4 l-.YA lguard-hex, F, adapted lfor enclosing the ypawl and ratchet 'of a brake-sLanderd,- substantially as described. f y Y A y 2.
